Short summary
We report the characteristics and performances of a cavity ring-down spectrometer (CRDS) designed for field measurements that uses light absorption at 662 and 405 nm to detect different reactive nitrogen species or group of species in the gas phase, either directly or after thermal decomposition. We report improvements compared to currently existing instruments, and describe the corrections applied to the raw data to account for chemical and optical interferences.
